Q

Explain Multi AZ Deployment

A

SYNCHRONOUS

Amazon RDS Multi-AZ deployments provide enhanced availability and durability for RDS database (DB) instances, making them a natural fit for production database workloads. When you provision a Multi-AZ DB instance, Amazon RDS automatically creates a primary DB Instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ). Each AZ runs on its own physically distinct, independent infrastructure, and is engineered to be highly reliable. In case of an infrastructure failure, Amazon RDS performs an automatic failover to the standby (or to a read replica in the case of Amazon Aurora), so that you can resume database operations as soon as the failover is complete. Since the endpoint for your DB instance remains the same after a failover, your application can resume database operation without the need for manual administrative intervention.

In RDS Multi-AZ, when a change is made to the primary database, that change must be successfully written to the standby instance before the transaction is considered committed.

IF asynchronous replication means that the primary database does not wait for the standby to acknowledge receipt of the data.
